Therefore, temperature is the key factor affecting the plastic deformation ability of magnesium alloys. The plastic forming temperature range of magnesium alloys is relatively narrow, generally in the range of 300-450°C. When the forming temperature is low, the deformation ability of magnesium alloys is poor, and it is easy to produce cold. Cracks,
